Cheers for the reply.
I guess with this kind of size of stop, I'd feel the chances of me getting stopped out would be extremely high. If I have an opinion (or am just trend following), I'd rather take the risk of losing £300, or 20% of my capital, and be able to ignore these fluctuations.
This is money I can afford to lose though (in fact it's all previous winnings), so I guess I'm being a bit more cavalier that is strictly advisable.
